The conductor(s) must fit loosely in the current sensor ("jaw ope-
ning"). Take care that while taking a reading, the conductor is loca-
ted as centrally as possible (in the centre of the opening).
Do not measure any currents in circuits in which
voltages greater than 1000 VDC or 750 VAC rms can
occur, to avoid damaging the measuring instrument
and endangering life as a result. Never measure
currents greater than 1000 A.
E Resistance measurement
Ensure that all circuit components, circuits, chips
and other test points to be measured are complete-
ly voltage-free.
To perform a resistance measurement, proceed as follows:
1. Connect the black test lead to the COM socket (centre) and the
red test lead to the "HzFOhm
2. Set the rotary switch to "Ohm" (200 - 2k - 20k - 200k - 2M -
20M).
3. Check the test leads for continuity by connecting both test pro-
bes with one another. As a result of this, a resistance value of ap-
prox. 0 Ohm must appear.
4. Now connect the test probes to the object to be measured. The
measured value will be displayed provided that the resistance of
the path being measured is not too high or open-circuit.
Notes!
When a resistance measurement is carried out, ensure that the
points of measurement touched with the test probes are free
